OS X html/php editor

I’m working on some sites, and I’m tired of using TextEdit for my code. If only it auto-indented and color coded.

Anybody know of a good html editor for OS X? I just want something that colorcodes my text, that’s all. PHP coloring would be really nice too.

I’m used to Dreamweaver, but I don’t need anything that powerful, and I was hoping for something free.
